CLOCK-CHIMES.

SPECIFICATION forming part of Letters Patent No. 747,408, dated December22, 1903. Application filed July '7, 1902. $erial No. 114,687 (Nomodel.)

To aZZ whom, it may concern:

Beit known that I, ADOLPH FUHRER, a subject of the Emperor of Germany,residing at Treorchy, county of Glamorgau, Wales, England, have inventednew and useful Improvements in Alarm-Clocks, of which the following is aspecification.

The present invention has reference to improvements in alar m-clocks,and relates more especially to means for actuating a series of clappersor hammers for the purpose of striking a like number of gongs, therebyproducing a melodious alarm-signal.

With this object in view the invention consists of the construction andarrangement of the various parts hereinafter described, and embodied inthe appended claim.

Alarm-clocks constructed on the American system generally have asinglebell-gong with a vibrating clapper or hammer, which upon the mechanismbeing started causes a loud signal to be given.

According to the present invention 1 use a set or chime ofbell-gongs,which are struck by a corresponding number of hammers for acomparatively long time after the mechanism has once been started.

In order to make the invention more readily understood, I haveillustrated it on the accompanying sheet of drawings, Figure 1 of whichshows a side elevation of a clock embodying my invention, unnecessaryparts being broken away. Fig. 2 is a vertical section on line AB of Fig.land Fig. 3 isa transverse sectional elevation on line CD of Fig. 1.

The ordinary starting device used in connection with the setting-dialacts on the disk 0, and as soon as this is freed the spring ,2 comesinto play, actuating the wheelwork of the alarm journaled between theplates Z. The arbor f, which is connected with the toothed wheel q, Fig.3, by means of a pawl, serves a double purpose. It is the winding anddriving spindle for the wheelwork and also carries the drum 75, upon thecircumference of which a number of fingers t' are provided. These latterupon rotation of the drum actuate successively the tail ends of thehammers h for sounding the bell-gongs g.

The drum 2, is keyed to a sleeve on the arbor I f, which turnsindependently of the axle and also carries a toothed wheel d. Anintermediate toothed wheel keyed on the arbor n meshes with the toothedwheel d and turns the drum as long as the alarm mechanism is inoperation. As the number of revolutions of the drum t differs from thatof the arborf and the former moves only in the direction of the arrow,Fig. 2, the parts d andt are rigidly connected by the sleeve and turnedfreely on the arbor f.

The hammers 7b are pivoted on a shaft p, which preferably is one of therods connecting the plates Z. The springs r are secured to the hammers alittle above the pivot, as clearly shown in Fig. 2. The fingers t' onthe drum t are arranged in three different vertical planes, so that thetail ends we of the hammers are engaged successively by the pins, so asto sound a chime on the tuned gongs. A stop 1') prevents the hammersfrom swinging too far and serves to lift the hammers off the gongs assoon as the latter have been struck, so as not to interfere with thevibrations of the gongs. The three gongs g are fixed on a horizontal pinextending from the bent bar or support so. This support may be extendedand provided with a ring for hanging up the clock or for more easilycarrying it.

Although I have shown in the drawings but three gongs, it is obviousthat I may employ a greater number, tuning them so as to form a chime.

What I claim, and desire to secure by Letters Patent, is

In a chiming-clock, the combination with the time-movement thereof, of aplurality of gongs arranged partly within one another, a correspondingplurality of hammers freely oscillating upon a pillar connecting the twomovement-plates, helical springs ordinarily keeping the said hammers intouch with the said gongs, a mainspring, an arbor connected thereto, anindependently-movable sleeve on said arbor, a toothed drum keyed to saidsleeve and freely rotatable upon the mainmy invention I have signed myname in pres spring, arbor between the movement-plates ence of twosubscribing Witnesses.

and adapted to successively actuate the said 1 u I hammers, and meansfor temporarilyactiiit; L s ADOLPH FUHRER' 5 ingthe said drum,substantially as and for Witnesses:

the purpose set forth. J. M. JOHNS,

In testimony that I claim the foregoing as E. L. PHILLIPS.
